On the 2024-2026 Hyundai Elantra, the newest Elantra Hybrids are subject to a recall covering the hybrid power control unit, the assembly that houses the inverter and DC-DC converter and manages power flow between the high-voltage battery, the drive motor and the 12V system. The HPCU assembly may overheat. Thermal events in an inverter of this kind typically show first as a hybrid-system warning and a forced power derate, and can end in a loss of drive power; the underlying risk with any overheating high-voltage power electronics is a fire. This affects 2024-2026 Elantra Hybrid vehicles only - it is not a defect of the conventional 2.0L Smartstream Elantra, whose driveline has no HPCU at all.

Common Symptoms

  • Hybrid system warning lamp illuminates
  • Sudden reduction in available power / limp mode
  • Loss of drive power
  • Warning message to check the hybrid system

How to Fix

Free recall remedy. Under NHTSA campaign 26V308000 dealers install a software update to the HPCU at no charge - the software manages inverter thermal load rather than replacing hardware. Owners should verify VIN eligibility at nhtsa.gov/recalls and get the update promptly rather than waiting for a symptom, since the campaign is preventive. If the hybrid system warning lamp, a sudden power derate or a burning-electrical smell appears, stop driving and have the car towed rather than continuing.

Typical repair cost:$0 - $0
